Information from Form Labs regarding Dental SG
Resin Tank Wear and Dental SG Resin
Dental SG resin causes the resin tanks to cloud and wear faster than other Formlabs resins. This clouding will eventually have an effect on the accuracy of prints. Use a new resin tank with each new Dental SG resin cartridge. For extremely high accuracy, switch resin tanks more often.
For the Grey resin the guide is to change every 2 liters of resin but customers can experience longer usage per tank.
Tanks Are Consumables
One tank lasts for about 2 L of our resin. With a separate tank for each individual resin color, switching materials is as easy as sliding in a new tank.
